Description

Technical Field

[0001] The invention relates to a hidden aging detection device. Background Art

[0002] The significance of aging test on equipment is mainly as follows:

[0003] 1. Determine product quality: Aging tests can help manufacturers determine the quality level of their products. Through aging tests, manufacturers can understand the life, performance, reliability and other aspects of the product, thereby further improving product design and manufacturing processes and improving product quality levels.

[0004] 2. Reduce quality issues: Aging tests help manufacturers find and solve potential quality issues before products are put on the market. Aging tests in the laboratory can find possible defects and failures before the product is officially put on the market, so that improvements and optimizations can be made in time to reduce quality issues and customer complaints.

[0005] 3. Reduce maintenance costs: By conducting accelerated aging tests in the laboratory, manufacturers can predict possible failures and damages that may occur in actual product use, thereby preparing maintenance materials and tools in advance and reducing maintenance costs.

[0006] 4. Improve customer satisfaction: Aging testing helps improve product stability and reliability, thereby improving customer experience and enhancing customer trust and loyalty to the product.

[0007] 5. Ensure that the equipment performs well during its service life: Equipment aging testing is a key step to ensure that the equipment performs well during its service life. Through multiple periodic tests, equipment aging testing can verify the durability, reliability, and performance stability of the equipment, thereby improving the reliability and service life of the equipment.

[0008] Temperature test is the most common aging test method. In the prior art, an aging cabinet is used for aging test. The aging cabinet in the prior art uses multiple independent cabinets for aging test. At the beginning of the test, the operator needs to open the cabinet door and then put the tools to be tested into the aging cabinet until all the cabinets are filled, and then start the aging test. After the aging test is completed, they are taken out one by one and tested by high-voltage heads one by one. The efficiency of this aging test method is extremely low.

[0047] See also Figure 1 , Figure 2 and Figure 3The aging detection device for hidden detection shown in the figure includes a lower cabinet 1, an upper cabinet 2, a hoist, a circulation fixture 8 and a controller 9. A cabinet door 1234 is installed at the front of the lower cabinet 1. The upper cabinet 2 is assembled on the top of the lower cabinet 1. A workbench 3 is formed at the top of the lower cabinet 1 and located in the front of the upper cabinet 2. An opening 301 connected to the inner cavity of the lower cabinet 1 is provided at the left position of the workbench 3. The hoists are provided in three sets, namely a first hoist 41, a second hoist 42 and a The third elevator 43 is installed at the rear of the lower cabinet 1, corresponding to the opening 301, and the first elevator 41 and the second elevator 42 are installed. The first elevator 41 is responsible for feeding downward, and the second elevator 42 is responsible for discharging upward. A high-voltage device 5 is installed through the upper cabinet 2. The high-voltage device 5 is equipped with a high-voltage head 51 that can be raised and lowered. The high-voltage head 51 is directly opposite to the second elevator 42 responsible for discharging upward. A transverse conveyor 6 is arranged inside the lower cabinet 1. The transverse conveyor 6 is moved up and down. Two are arranged in parallel. Inside the lower cabinet 1, the third elevator 43 is installed at the right side of the transverse conveyor 6. The circulating jig 8 carries the tool to be tested for aging and is transported downward by the first elevator 41 to the position opposite to the bottom transverse conveyor 6, and is hooked and transported by the transverse conveyor 6 to complete the first stage of aging test. When the circulating jig 8 reaches the third elevator 43, it is lifted to the upper transverse conveyor 6 by the third elevator 43, and is hooked and transported by the upper transverse conveyor 6 to the position where it reaches the second elevator 42, and is lifted upward to the top of the workbench 3 by the second elevator 42. At this time, the high-pressure head 51 goes down to apply high pressure to the tool to be tested, and the test data is stored and displayed through the controller 9; the lower cabinet 1 and the upper cabinet 2 are equipped with a heat dissipation system 12; the elevator, the heat dissipation system 12, and the transverse conveyor 6 are all connected and controlled by the controller 9, and a start switch 1235 connected to the controller 9 is installed at the front end of the lower cabinet 1.

[0048] In the above technical solution, each time the start switch 1235 is pressed once, the entire device completes a set of actions.

[0049] A set of actions is as follows:

[0050] The circulating jig 8 carrying the aging test tool is lowered into the lower cabinet 1 by the first elevator 41 and slides to the corresponding lowered transverse conveyor 6 .

[0051] After the transverse conveyor 6 is extended, the circulating jig 8 is hooked in. At this time, the circulating jig 8 located at the end of the lowered transverse conveyor 6 is ejected and ejected to the third elevator 43.

[0052] The third elevator 43 lifts the ejected circulating jig tooling 8 and moves it upward to the upper transverse conveyor 6. At this time, the upper transverse conveyor 6 hooks the circulating jig tooling 8. At this time, the circulating jig tooling 8 at the left end of the upper transverse conveyor 6 is ejected to the second elevator 42.

[0053] The ejected circulating jig 8 is lifted by the second lifting machine 42 and moves upward to the surface of the workbench 3 .

[0054] At this time, the high-pressure head 51 acts on the tool being tested after descending, and transmits the data of the tool being tested to the controller 9, which stores these data for subsequent export, and displays the test data of the tool through the 10-inch display of the controller 9 for easy reading by the staff.

[0055] The above steps are repeated until all the tested tools are tested. At this time, the unloaded circulation fixture tooling 8 continues to enter the lower cabinet 1, and the heat dissipation system 12 dissipates heat synchronously to discharge the heat inside the lower cabinet 1.

[0056] See also Figure 4 , Figure 5 and Figure 6 As shown, the elevator includes a frame plate 401, and two pulley groups 402 are arranged at the upper and lower sides of the back of the frame plate 401. A conveyor belt 403 is rotatably arranged between the upper and lower corresponding pulley groups 402. A driving motor 404 for driving one of the pulley groups 402 to rotate is installed through the frame plate 401. A notch 405 is arranged at the front side of the frame plate 401 at the position corresponding to the conveyor belt 403. Guide rails 406 are installed on both sides of the notch 405. A conveyor belt 403 is slidably arranged between the guide rails 406 on both sides. A slide plate 407 is provided, and the slide plate 407 is fixedly connected to the conveyor belt 403 via the slot 405. With the forward and reverse rotation of the driving motor 404, the slide plate 407 slides up and down along the guide rail 406. A support platform 408 is installed through the slide plate 407, and pulleys 409 for supporting the circulating jig 8 are arranged at the front and rear sides of the support platform 408; a plurality of positioning rods 410 are installed through the support platform 408, and positioning wheels 411 for positioning the circulating jig 8 are arranged at the upper ends of the positioning rods 410.

[0057] In the above technical solution, the circulating jig tooling 8 is positioned by the positioning wheel 411, so that when the slide plate 407 slides up and down along the guide rail 406, the circulating jig tooling 8 is prevented from sliding out laterally. After the circulating jig tooling 8 is lifted into place by the elevator, it is pulled by the transverse conveyor 6 to separate the positioning wheel 411 from the circulating jig tooling 8. At this time, the circulating jig tooling 8 slides to the top of the transverse conveyor 6.

[0058] See also Fig.12 and Fig.13 As shown, the transverse conveyor 6 includes two insulating seats 601 arranged in parallel, and a conductive wheel 602 rotatably matched by the insulating seats 601, and multiple conductive wheels 602 on the same side are connected in parallel, the insulating seat 601 is U-shaped, the opening of the insulating seat 601 faces upward, and the conductive wheel 602 partially extends to the outside of the opening, and a connecting rod 603 is arranged between the bottoms of the two insulating seats 601, and an electric telescopic rod 604 is installed at the connecting rod 603 on the side close to the first hoist 41 and the second hoist 42, and the output end of the electric telescopic rod 604 is provided with a hook pull component 61 that cooperates with the circulating fixture tooling 8.

[0059] In the above technical solution, the circulating jig tooling 8 is powered by conducting current through the conductive wheel 602, and the conductive wheel 602 can also play a role of rolling support for the circulating jig tooling 8, allowing the circulating jig tooling 8 to pass through the transverse conveyor 6 more smoothly.

[0060] See also Fig.13 and Fig.14 As shown, the hook pull assembly 61 includes a slide plate 610, the slide plate 610 is fixedly connected to the telescopic end of the electric telescopic rod 604, and one or more slide grooves 611 are arranged on the surface of the slide plate 610. The slide grooves 611 are arranged vertically, and a slider 612 is slidably arranged in the slide groove 611. The upper end of the slider 612 is provided with a guide inclined surface 613, and a base block 614 is provided at the bottom of the slide groove 611. A guide rod is provided on the top of the base block 614. The guide rod The rod is inserted into the slider 612, and a spring 616 is sleeved on the guide rod, and the spring 616 is connected between the slider 612 and the base block 614; the guide slope 613 cooperates with the circulation jig fixture 8, and the spring 616 is compressed at this time, and the slider 612 hooks the circulation jig fixture 8. As the electric telescopic rod 604 retracts, the circulation jig fixture 8 slides from above the pulley 409 to the conductive wheel 602; and is transported in the direction of the third elevator 43.

[0061] In the above technical solution, when the electric telescopic rod 604 is extended, the upper end of the slider 612 contacts the circulating jig fixture 8, and under the action of the circulating jig fixture 8, the spring 616 is compressed. When the hook-pull assembly 61 passes under the circulating jig fixture 8, the spring 616 rebounds. At this time, the slider 612 hooks the circulating jig fixture 8, and through the retraction of the electric telescopic rod 604, the circulating jig fixture 8 located on the elevator is hooked onto the transverse conveyor 6.

[0062] The guide slope 613 facilitates the sliding block 612 to be pressed down after contacting the circulation jig 8 .
